FAQ

Q1: How do I confirm these valves will fit my specific Volvo D13 engine?
A: The 20740798 (intake) and 20768519 (exhaust) valves are standard OEM replacement parts for the Volvo D13 and D13f engine families. To confirm fitment, we recommend checking your engine’s serial number and comparing it to Volvo’s parts catalog. Alternatively, you can remove one of your existing valves and measure its stem diameter, head diameter, and overall length to match against the specifications of these parts.

Q2: Can I install these valves myself, or do I need a professional mechanic?
A: Valve replacement is a complex engine repair task that requires specialized tools (such as a valve spring compressor) and technical knowledge. It involves removing the cylinder head, cleaning the valve guides, and properly seating the new valves. We strongly recommend having this work performed by a certified diesel engine mechanic to ensure correct installation and avoid engine damage.

Q3: What maintenance should I perform after installing new intake and exhaust valves?
A: After installation, it is critical to properly break in the new valves. Follow the engine manufacturer’s recommended break-in procedure, which typically involves running the engine at varying loads for a specific period. After the break-in, check and adjust the valve clearance (lash) as per the service manual. Regular oil changes with the correct viscosity oil will also help extend valve life by ensuring proper lubrication of the valve stems and guides.
